Scientists Find Million-Year-Old Bacteria in Mammoth Bones

Scientists at the Center for Paleogenetics have uncovered the oldest host-associated bacterial DNA ever found — from mammoth remains over 1 million years old. 🔍 What they discovered: Microbes like Streptococcus, Pasteurella, and Erysipelothrix that may have caused fatal diseases. One bacterium closely related to Pasteurella multocida, which caused deadly outbreaks in modern African elephants. DNA that shows how microbes coexisted with mammoths for hundreds of thousands of years. 🌍 Why it matters: This research pushes the limits of ancient DNA science, revealing how bacteria may have influenced mammoth evolution, health, and even extinction. It also raises new questions about the deep history of disease in megafauna and their modern relatives like elephants. Would you want scientists to one day reconstruct an extinct animal’s entire microbiome — not just its DNA? 💬 Share your thoughts in the comments. 🔔 Don’t forget to subscribe for weekly discoveries in science, paleontology, and genetics.
